IPC: G02F1/1368
Filed: 1993-12-22
Abstract: A liquid crystal display device of the active matrix type which prevents residual of charge in liquid crystal picture elements with respect to time. The active matrix liquid crystal display device includes liquid crystal picture elements formed from a liquid crystal layer held between picture element electrodes arranged in a matrix and common electrodes opposing to the picture element electrodes, and picture element transistors corresponding to the liquid crystal picture elements. While a predetermined reference potential is supplied to the common electrode, image signals are applied to the individual picture element electrodes by way of signal lines and picture element transistors to effect ac driving of the liquid crystal picture elements. Discharge means for connecting the common electrodes and the picture element electrodes to an equivalent potential to each other is provided to discharge the charge remaining in the liquid crystal picture elements thereby to prevent the variation of the reference potential.

Abstract: A roller shade assembly (10) for motor vehicle applications. For covering an interior compartment area (12) of a motor vehicle. The assembly of this invention is mounted in such a manner that the flexible shade panel (18) is extended in a direction transverse to the longitudinal axis of the vehicle, or in the "cross-body" direction. This orientation eliminates the requirement that the roller tube assembly (16) be removable from the vehicle to avoid obstructing the cargo compartment (12) when large items are placed in it or when the cargo compartment (12) is enlarged by folding forward a rear seat back (14). The configuration further enables the shade (18) to be extended and retracted either from the rear vehicle cargo door (13) or from within the vehicle.

Abstract: A data processing system (10) and method for performing a snoop-retry protocol using an arbiter (14). Multiple bus masters (12, 16, 17) are coupled to multiple shared buses (20, 22, 24, 26). Each bus master (12,16,17) may initiate a bus transaction ("initiating master"), or snoop the bus transaction ("snooping bus master") occurring on a shared bus (20). When an initiating processor requests access to a dirty cache line in a memory (18), a snooping bus master asserts a shared address retry (ARTRY*) signal to inform the initiating processor to relinquish ownership of the shared bus (20) and retry the bus transaction. Upon detecting the shared ARTRY* signal, all potential bus masters remove their bus requests and ignore any bus grants from the arbiter (14), thus allowing the snooping processor which asserted the ARTRY* signal to gain ownership of the shared bus (20) to perform the snoop copyback. The arbiter (14) provides simple arbitration support to guarantee the update of the memory 18 has the highest priority among masters (12, 16, 17).

IPC: B01D17/02
Filed: 1993-04-28
Abstract: A filter having improved means of positive shutoff employs a rigid tubular fuel pervious core surrounded by flexible filter media that intercepts and resists the passage of particulate matter and water. A tubular retention sleeve is positioned within and in dosed communication with the tubular core at one end thereof, the retention sleeve having an integral ball retention portion of reduced internal diameter. An end cap is sacred to the other end of the tubular core member and has an annular sealing surface surrounding a flow passageway opening therethrough. A ball is normally positioned within the retention sleeve and in the engagement with the circumferential ball retention seat. When the flexible filter media has absorbed a sufficient quantity of water the pressure differential across the ball forces it to pass through the retention seat and to lodge against the sealing surface of the end cap, thereby closing further flow through the filter.

Abstract: A thermally conducting reflecting envelope (11) for use in laser cavities, and laser apparatus (10) employing such envelopes (11). A transparent heat conducting member (17), such as sapphire, surrounds a laser medium (12) and has a transmissive coating (13) thereon that transmits pump light provided by a pump light source (20) onto the laser medium (12). The coating (13) reflects the diode pump light and transmits laser light to suppress ASE that causes clamping of the laser output at a relatively low level. An absorbing elastic material (15) is disposed on the dielectric coating (13) and is adapted to absorb the laser light. Heat sinks (16) are disposed in contact with the absorbing elastic material (15), and conducts heat away from the laser medium (12). A light entrance window (13a) or area is antireflection coated to transmit the pump light onto the laser medium (12). A liquid cooled version further includes a liquid cooling channel (18) disposed between the laser medium (12) and the thermally conducting member (17). The present invention provides more efficient cooling and a more effective ASE suppression than conventional Samarium glass filters in solid state lasers pumped by flashlamps or laser diodes. The present invention provides for efficient heat conduction and removal from a laser medium, efficient transmission and absorption of laser light to suppress ASE, and efficient transmission of pump light to the laser medium.

Abstract: A method of partitioning a pre-selected phase of a sample of liquid having a plurality of phases of differing densities, a separation device and a tube containing the separation device. The sample of liquid is placed in a first chamber of a linear tube that is separated from a second chamber by a separation device. The separation device slidably engages the interior surface of the tube in an essentially fluid-tight manner and has an axial orifice on the longitudinal axis of the tube that is in fluid flow communication with a flow-restriction channel. The phases are ordered concentrically by rotating the tube around its longitudinal axis e.g. in an axial centrifuge. The volume of the first chamber is reduce by movement of the separation device within the tube, that phase of the liquid located axially within the first chamber flowing into the axial orifice and passing through the flow-restriction channel into the second chamber. The reduction of the volume of the first chamber is controlled using phase-separation information. The method is useful in separation of blood components.
